Layer Two Technology

Definition ∞ Layer Two technology refers to protocols built on top of existing blockchain networks to improve scalability and transaction speed. These solutions process transactions off the main blockchain, or Layer One, before settling them back onto the primary chain, thereby reducing congestion and transaction fees. Examples include rollups, state channels, and sidechains. Layer Two technologies are critical for enabling broader adoption of decentralized applications by addressing the throughput limitations of many foundational blockchains.
Context ∞ The progress and deployment of Layer Two technologies are central to ongoing discussions about blockchain scalability and the future of decentralized applications. News frequently reports on new Layer Two solutions, their adoption rates, and their impact on network performance and user experience. These advancements are essential for facilitating a more efficient and cost-effective digital asset ecosystem.
